Construction and application

The SK20 cam switch allows manual switching of circuits in the 0-1 position, making it an ideal solution for controlling lighting, heating devices or other electrical consumers. The construction with a yellow-red front provides clear visual identification of the switching status. Front panel mounting is simple and intuitive, and the IP65 degree of protection guarantees safe use even in harsh environmental conditions. Designed for indirect mounting, which provides flexibility in choosing the installation location.

Key features and benefits

• Durability and reliability: Made of high-quality plastic, resistant to mechanical damage and external factors.
• Safety of use: IP65 protection degree protects against access to live parts and against the influence of moisture and dust.
• Convenient operation: The knob provides smooth and precise circuit switching.
• Versatility: Suitable for a wide range of applications – from industrial installations to home distribution boards.
• Designed for high loads: Rated continuous current of 20A and rated power of 4kW (AC-3, 400V) allow connection of demanding consumers.
• Easy installation: Designed for mounting on the panel using screws.
• Clear status identification: Yellow-red front makes it easy to quickly recognize the switch position (0 or 1).

Technical parameters in practice

A rated continuous current of 20A means that the switch can safely operate with a load of this value for a long time without the risk of overheating or damage. The rated power of 4kW at a voltage of 400V allows you to connect devices with significant power, making it an ideal solution for workshops, production halls or homes with high energy demand. The lack of auxiliary contacts makes it a simple and effective solution for basic switching applications. Screw connection ensures a secure and durable connection of wires.
